HIKARI ANTI RAIN is a window-glass coating designed to create a high water-repellent layer on automotive glass. It is positioned as a durable glass treatment with good wear resistance against wiper friction, and uses a hybrid structure (fluorine + silicone) to form a nano-level repellent film on glass.

Use it on windshield, side windows, and rear glass to help water bead and roll off, improving visibility in rain.

Step-by-step use (simple):

1. Wash & decontaminate: remove dirt and oily film (best results on fully clean glass).
2. Dry completely.
3. Apply: put a small amount on the applicator/cloth and spread thinly over the glass (work in small sections).
4. Set: let it sit briefly until a light haze appears.
5. Buff: wipe off residue with a clean dry microfiber until clear.
6. Cure: avoid water for a short period after application (follow package guidance).
